That's actually a tricky one.
For example not everyone has the ability, training nor aptitude to be a heart surgeon. However, more people have the ability, training and aptitude to be cleaners.
Yet both are vital functions within our society. (I really hate it when people look down on those who carry out essential functions that enable society to function - think of those expensive car drivers who give London bus drivers a hard time on the road.)
This comes back to "each according to their abilities and needs."
The problem is in this celebrity-obsessed world, glamour models and footballers earn far more for doing far less. It's especially the case with glamour models - perpetuated by "mens" magazines and the tabloid newspapers that send out messages to people that this is a reasonable way to make a living. I personally think that people are capable of much more positive things than stripping off for a camera or selling a warts-and-all tale of sex with a footballer/soap star in the hope that it will lead to a career in glamour modelling.
